My brother just came back from a job interview where he had to have a Hair Follicle drug test done. Him and I smoked about a month ago, he only smokes 1 hit like 5 times a year, he literally only had one hit if this joint. After a long heated discussion we got into a huge argument because I told him that Hair tests can go back 90 days where he says that one hit will not even show up on the test.

Can someone please put some light on this for us? Some real life example would help, maybe someone who was in this situation that pass/failed a hair test?

1 hit will not show up on a hair follicle. no way. THC is stored in your fat cells. the less you have the quicker it leaves your system. if your brother is 400 pounds he could still have a trace, but at that weight 1 hit would be dilluted much more than a skinny person and would not show up.

really? That's interesting to hear. From the research I have done on google, most people seem to agree that it stays in your hair for around 90 days. So when they do this test it just checks the THC level? It wont tell them when and now much you smoked? Damn, He might have been right... I hate losing to his smart ass!

wrong, it will show up if u were in the same room as someone smoking weed.

All the answers you will get are guesses and speculations. The only real answer is to take the test and wait for the results. Don't bother shaving your head or whole body for that matter, that will send them enough signals unless your an Olympic swimmer.
